Description

Semisealed beam lamp for H3 halogen electric-light bulb}

The present invention relates to a semi-shielded beam lamp mainly used for lighting or auxiliary lamps such as various means of transportation and construction heavy equipment, and in particular, it is possible to use a small size and high intensity H3 type halogen bulb, but the lens and reflector It is made of Pyrex-grade borosilicate glass, which is excellent in waterproof and moisture proof effect, and has excellent weather resistance and thermal shock resistance, and can be used for lighting and auxiliary lights of various transportation means and construction heavy equipment.

The first shielded beam lamp is made of glass with both the lens and the reflector, the filament is fixed and installed in the reflector, the welded lens and the reflector, and the inside of it is a single shielded beam. The lamp has only one light bulb, and when the filament is short-circuited, the entire shield beam lamp needs to be replaced.

In view of the above problems, the conventional semi-shielded beam lamp (semisealed beam lamp), which is pre-filed, as shown in FIG. 1 of the present invention, has a lens 10, a reflector 20, a light bulb 40, and a stopper 50. It consists of.

First, the lens 10 is formed in a smooth container shape using a glass material, and the reflecting mirrors 20 are formed of a synthetic resin or metal material having excellent heat resistance and hardness, and are bonded to each other, but the threads are formed on the rear center of the reflecting mirror 20. (22) and the socket 21 is formed with a light bulb seating groove integrally with the reflector 20, the screw cap 51 is a closed cap 50 is machined so as to be engaged with the thread 22 of the socket 21 ) Is configured separately.

In addition, the bonding portion of the lens 10 and the reflecting mirror 20 has a configuration in which a bonding protrusion and a bonding recess are formed and then bonded by injecting an epoxy-based strong adhesive.

In the conventional semi-shielded beam lamp configured as described above, the socket for storing the bulb is uniformly made based on the size of the H4 halogen bulb, and thus it is not possible to insert and use a small size and excellent illuminant H3 halogen bulb. It implies

In addition, since the lens and the reflector are made of materials having different physical properties, it is difficult to maintain airtightness even after integrating. In particular, when using an adhesive such as epoxy, it is vulnerable to the heat generated from the light bulb, so that the adhesive part is long-term Due to the emulsification, the pores are generated due to the self-weight of the lens, and the waterproof and moisture-proof effects are lowered, which results in a short circuit, which may result in another problem that the battery is discharged.

The present invention is conceived in view of the above situation, by mounting a separate auxiliary socket made inside the main socket manufactured integrally with the reflector, it is possible to insert a small H3 type bulb, the auxiliary socket It is another object of the present invention that the black spot is not generated when the light is irradiated by integrally including the sub reflector and the sub reflector.

In addition, the lens and the reflector are made of Pyrex-grade borosilicate glass having the same physical properties, and the inside of the reflector is deposited and plated to make a thin layer on the surface by heating and volatilizing a metal in a vacuum. It is another object of the present invention not to be deformed or dissociated by heat even when used for a long time through a glass welding with a glass welding, and to achieve perfect waterproof and moisture proof.
